Anomalous Diffusion in Intermittent Chaotic Systems

Abstract
It is shown that anomalous diffusion (i.e., nonlinear growth of mean square displacements) can be caused by a specifically chaotic mechanism. It depends on deterministic diffusion and intermittency and gives rise to mean square displacements which grow asymptotically like tν with 0<ν<~1 or like tlnt, depending on universality classes.
